How to Unlock a Car Engine That's Locked?

[DavidRose]

Here are the solutions for a locked car engine: 1. The solution is to simply use the key to unlock it. Generally, aftermarket keys have poor recognition, so it's best to use the original key. If even the original key cannot unlock it, then wait for the engine protection data to clear and reconnect the battery to unlock it. Simply disconnect the power for about 10 seconds and then reconnect it. 2. If the engine is locked due to external reasons, such as a collision causing the engine to sink and lock, then it definitely needs to be repaired. If it's locked because the computer system detected non-system-certified components, it's recommended to go to a 4S shop or a qualified repair point for unlocking.
